I have recently had to adopt hearing aids. I shall soon be taking them back to supplier for adjustment/repair/replacement of one of them. What seems to happen is that with new (lithium) battery it gives sign of life and some amplification into the right ear, but after a few hours there is no more signal - what I hear is the same whether I wear it or not. Whereas the left aid, which must be set for a higher amplification (for less good ear) works for the 4 or 5 days asit is expected to. So it is sounding to me as if the right one is delivering just enough amplified signal to hear when battery is new, but as it is used the power soon decreases to inaudible.
It slightly surprises me. Obviously a battery can never deliver constant power for ever. But I would have thought it a fairly trivial, or at least standard and solved engineering problem to deliver a nearly constant power for a few days.
I will work this out that the supplying clinic, but would like to have some comment whether my engineering conjecture Is reasonable.
